Welcome to Librarium Online!
I ahve not read any of the fluff on Tyranids beyond the stuff in the Codex and I wanted to ask those of you that have if there is any precident for the Tyranid infesting vehicles or their crew (Zerg-like) and using said vehicle. I ask because I wanted to see if there is any semi-fluffy way to use vehicles in Apocalypse games.
I think if Zerg can do it, Nids can do it too!
But as far as I know, you can use the Genestealer Cult backgrounds to allow vehicles in your game.

Daemon Hunters Win / Draw / Lost 
You can use the Genestealer cults as the reason, but an even easier way is that it is an ally doing it. As we can ally with CSM this gives us access to every human vehicle.
Using the Ally Matrix provided in the Apoc. rulebook there are only two armies that you cannot easily get stuff from, which I believe are Eldar and Necrons. So there is plenty of room to use vehicles. Just image a group of 'Fexes running with a battalion of Baneblades. Fun times.
For Apocalypse games, you can pretty much make up any reason that you want to and it's valid. Genestealer cult, allies, etc... it all works. I've often given thought to getting a baneblade and modding it up with some stealers in and around it for appoc games.
Allies? We don't ally with other races, we consume them, all of them. I don't think I have looked at the exact rules for selecting allies. If you want the vehicle to be infested with Tyranid stuff I think you could do it. Technically speaking in fluff a Genestealer cult will never ally with Tyranids. The cult comes under the control of the Hive mind and is immediately consumed as biomass when the Hive fleet arrives. However a Genestealer cult would be an easy way of doing it. And the cult could provide a chance to paint some kind of cult marking onto the vehicle. I think that an infestation would be more fun though. I have thought about it and having some crewmen with tubes in their heads controlling their brains all linked to a symbiote critter would be cool.
I justify using my Eldar and nids together by saying that the Eldar are a pirate fleet who captured a small hive fleet (after it finished defeating another hive fleet and was in a weakened state) and psychically control the nids as a bio-weapon to cover up their own predations.
