Not exactly sure how well it would fit, but I'd imagine that some have used slim fans as pushers, while keeping A/C. Slim fans are literally pretty damn slim, so I'd think that you could put them in front of the radiator with no issues.
You could still use them as pullers, though. I dogged the hell out of my T25, and the only thing I changed was added a Z32TT radiator cap (16psi). I only ran it with one fan, too. Never saw anything over 210.
