An alternative strategy, for a more interesting late game, is to focus on Spain. Hold Sicily for as long as you can, but do not divert undue forces there. Keep what you have, and send a few Libyans from Carthage every now and then. Use your navy to cut Messana off from Capua, and have yourself a nice little set of battles against a reasonably sized force. Your best bet for doing this is to SURROUND the port of Capua. Ships can escape a blockade without a fight, but not a circle around the port. Use Carthage to crank out Triremes, and Palma(and Carlais, if you hold it) to pump out Biremes. These will keep your power at sea unchecked. Make sure you decide how important Caralis is. If you decide to fight for it, then move your starting forces from Thapsus, accompanied by 1 or two hired Numidian Cavalry, and sail them North. Place them in a city or use them in ambush, your choice.
Sicily is not nearly as vital as it is sometimes made out to me. It is worth holding, but if you are in the mood for a late game duel with Rome, it isn't worth taking. It can provide a valuable training ground for men and anti-Roman tactics. You can choose what to do with Syaracuse. Taking it early requires money, money that could be spent in Triremes for cutting the Scipii in half, and it also streches your forces particuarily thin on the Island. An alliance with the Greeks, or if they offer you status of protectorate, is my preferred choice. Use your army, from a central point, to help the Greeks in battle, and to defend Lilybaeum. Beyond that, Sicily isn't that important. Other than a few Libyans from Carthage, and the retraining of the original elephants, use only men from Lilybaeum to defend Sicily. Focus Carthage on shipbuilding, and Thapsus on growth. When you can train Libyans in Thapsus, create an army of Iberians, Libyans, and Long shields, as well as a few Skirmishers, and March into Numidia. The problem with Carthage is that it has no real infantry and cavalry producing Backbone, anywhere. Numidia provides this. You don't have to take all of it, Ignoring Lepcis Magna was a good suggestion. You just need three to four territories for army production.
The most important conquest you have to make is Spain. Transfer the Baelarics from Palma, as well as a few Libyans/Long shields from Carthage. Give Corduba a temple to Tanit, and watch things happen. Take Carthago Nova early. It is an effective Springboard for defeating Spain. From There, drive the Gauls(Through bribery, assaination, whatever) from Spain. Preserving Peace is for the best, but not needed. From There, Spain is at your mercy. I keep Scallabis and Asturica alive for training purposes, but the choice is yours. Just make sure no Bull Warriors are produced and you will be fine. After Spain is under your control, turn it into an economic base, like Numidia will be your military one. Use temples to Tanit to get to 6000 people, then switch to Execution Squares and Milqart. Build a network of Roads, and upgrade Mines, Soon it should be producing the wealth needed to fund an empire, even if you lost Lilybaeum. From there you have several choices. I typically gather my best men in one army and take Sicily, retrain, move to Spain, make Gaul a protectorate after taking Narbo Maritus or Massila, and then I follow Gallic armies around, helping them to establish dominance. After a few years of that, I retake Northern Italy for Gaul(If the Julii have taken it) and then I march into Italy from the North. The Scipii should be a non threat, simply for lack of money, but the Julii, Senatem and Brutti each possess sizeable forces, even some after marius units. After I pillage Italy and gift it to Macedon (Except Rome) in exchange for trade and protectorate status, the world is open. All regions should be sufficently developed that they will pose interesting challenges. I typically bribe Southern Gaul, then move on and take almost every coastal region not under Macedonian control. The Selucids, if alive, are particuarily fun, because they have such diversity. As are the Pontics.
This is probably a little late, seeing as you already started, but when you win your current campaign, maybe it is worth a try.
Good Luck.
