BRPE and DRPE were punches only.  The succession of letters suggests
there might have been ARPE and CRPE, but if so they never made it into
production.

Reader: there were a BX and CX and DX and that suggests there was an
unsuccessful AX.

In principle you could make an R-T set by mounting 8-level items on the
5-level RT stand - but you'd need some things like tape reels to go with
it.

I remember my boss once was looking at a number of projects under way in 
R&D.  One was an 8-level R-T set.  He asked who the customer was - it was 
Pacific Bell.  He asked how many they were going to buy - and the answer 
was three.  I don't know if he got the project cancelled, but the obvious 
implication was that for only three sets Pac Bell could do their own 
engineering; Teletype shouldn't develop a product for which there was no 
market.  Another project in a similar vein was an 8-level keyboard typing
perforator.  Asked who the customer was, the reply was that one had not
been identified, but there was such a product in the 5-level line so they
thought there should be one for 8-level as well.
