In theory, yes, but the big-end crank pins would need measuring just to make sure.

This may present a big clearance issue between the crank pin/big-end from one crank and the web that it's pressed in to on the other.

I don't reckon big-end bearings will be much of a problem to replace. I bet something like TZ, RS, or even TZR bearings (something anyway - but you do need the speed rating of 13,000+rpm, which is why you can't just pop down to the local bearing factor on the trading estate!!) will be the same, and cheapish too.

For what you are intending, you will most definitely need to speak to a 2-stroke crank specialist. Go for one of the real reknowned proddy tuners like those mentioned in my first reply. Another well known name in 2-stroke tuning/racing circles is Graham File.
