Magnum Serpentine on a '91 TBI 318? Without changing the intake?

I've got a '91 Dakota with the 318 TBI and the serpentine belt tensioner visually looks to be on it's last legs. I've had the tensioner go bad once already and the truck was down until I found a used one in a JY. They are a one year only part and are no one makes a replacement. The likely hood of finding another one that is good seems slim.

The ultimate fix is the 5.9 SMPI swap I am working on. I have most everything but am still assembling things and am not quite ready to do the swap. I also need the truck for winter driving and am concerned that the swap could run into a snag and sideline the truck for an extended period of time when I really need it. I've been planning to do this swap during the summer, but missed that window for this year.

The temporary solution that crossed my mind was to swap a full Magnum serpentine front end onto the 318. I have all the parts, including the non-AC bracket. This would also allow me to replace the cracked radiator with the new '92 one I bought for the swap.

The only issue I can think of is that the TBI thermostat housing could potentially cause an issue. It points at the wrong side of the radiator and might crash with the Magnum alternator.

Just curious if anyone has done anything similar. I figure I will do some more inspecting and see what I see but thought I would just toss it out there to see if anyone has any experience.

Thoughts?

Thanks.
