How many clicks/positions? 3 = triple, 2 = double. But a 3-position triple
isn't that great - no trim.
(suck it and see! put both bikes next to each other, and run a cable from
the shifter to the other bike and see if it works)

I think you need to get a ruler out and find out the spacing, otherwise it's
impossible to make a sensible decision.

I still reckon 9speed of some form is the way forwards.
If the existing frame is 126mm, keep the existing hub, get new 9sp shifters
and chain, and put 8 of 9 on the hub.
If the existing frame is 130mm, you can get a new 8/9 speed wheel (they are
identical), new 9sp shifters and chain and put a 9 speed cassette on.
Alternatively you can get 7sp cassettes just as easily as 8sp - just get an
8sp and remove one of the cogs! Do this until the hub (freehub or bearings)
dies, then work out the next move - which should be to 9sp IMO.
Your front shifter can remain the same whatever you do.
