Reducing/flattening an Astro-Physics refractor

I already have the TOA-35R reducer/flattener for my Tak FS-102 (works perfectly), and was wondering, to same some money to use the same reducer/flattener in my Astro-Physics 12Ed refractor - see any issues?

Focal ratio of the Tak is f/8, the AP is 8.5. Focal lengths are close.

All I would need to do is have my mate turn up an AP to Tak adapter, then space it with the adapter I already have for the FS.

Or is this all bad physics and mathematics? Or just try the damned thing

I know the AP telecompressor is cheap enough (cheaper than the Tak), as are their parts, but I am still trying to be frugal
