[Leica] Am I being stupid? (R content)

Am I being stupid for considering an R at this time?

Here's my background: I shoot mostly film on a pair of M's, mostly at 50mm 
and 28mm.  I have a Canon 1V which gets some use, but I only have a 50 and a 
28 for it.  Some day I'll pick up a decent digital, but there's no rush for 
it now.

The dilemma: An R is sounding like a good idea.  I have no desire to shoot 
wide angle on it - the M covers that just fine.  This would complement my M, 
not replace/back it up.  I'm thinking of getting a 90, a 50, and maybe a 
macro if I find one for a good price.  The 50 only because it's useful and 
can be had for not all that much money.

Is this silly thinking?  Should I just get an 85/1.8 or 135/2 for my Canon? 
The 1V is a great camera, but can be a bit large.  The 50 is a bit 
underwhelming at times as well.  Or should I just get a 90/2 for my M?  I've 
already got a 90/4 for it.

If I do decide to pick up an R, which one would you recommend.  The R6.2 
looks nice and is small.  The R8/R9 is newer, has more features, but is 
larger.  The R7 has more features than the R6 and is most likely a lot 
cheaper - did this model have a lot of problems?

Interested in hearing your thoughts on this matter, or anything related.  I 
don't feel like working today :)
