I don’t have my cab near me so I’m going to try and mock a firewall to give me some perspective on how close the engine can/will be.
ogre: I wouldn't do it

thats kinda what I meant when I posted the link for adjusting gaps and using the driver's side mount as a cab pivot. unless you are using the original engine mounts then you don't really know exactly where the engine will sit, in comparison to the factory location, so you can't know how the new location will affect the fitment around the firewall, floor, etc. since the cab and other front sheet metal parts will possibly need to be shifted around to get the gaps and fitment right it is gonna be really hard to say if there will be interference when the parts get assembled all at the same time.
I would say if you can get the cab and front clip sheet metal then it may be worthwhile to do that and assemble the parts. then slip the engine and trans in place to get the mock up done.
thats just my opinion. it's your truck so you do what you think is best.
