After all the training with Ezio, and all of Leonardo's inventions with the hidden blade, I imagine Desmond having modern twin hidden blades and hidden guns. I also imagine the two hidden guns combined to become a modern and compact sniper rifle for long-ranged assassinations.
As for his conflict with enemies with guns, I think he stands fairly a chance melding with a large crowd on the cityscape. They could also equip him with a timed stealth camouflage or some sort. His speed in free-running also makes it hard for non-assault-rifle weapons to hit him.
These are all just my imagination concocting up some weird possible dream game in mind, but I think it's possible for a modern day Assassin's Creed to be fun.
