The slides themselves are not plastic, but a product called Rhinolite,
whatever that means.  8-)  I use the same film holders for IR and have no
problems.

You shouldn't have any problems, provided your slides are not old and / or
tatty.  Sinse you have promised that you wont leave them out in broad
daylight, then worry not.  8-)

The first thing to do, though, is to put a test sheet in the camera, pull
the slide, and test for bellows fogging.  Leave the camera out in the sun
for ten minutes and then dev it.

You'll find that a rubber or plastic, or even a faux leather bellows will
fog your film.

If the fogging is only mild, you could try to wrap the bellows in Aluminium
(you say potato, I say tomato) foil, as IR is block by the metal.

You are using different formats, different cameras, shutters and lenses.  On
top, the film dev rate will differ.

Either way, the amount of IR present in a scene is very dependant on the
time and type of day.

I would suggest you base your first experiments on suggestions posted here,
according to the subject matter you intend to shoot.

..due to the current economic situation, the light at the end of the tunnel
has been turned off until further notice.
