I would but you'd be the only one posting I'd be fine with that kind of thing in tech. Had some in Vintage over the years too.
I bought the bike already swapped from a guy in SC - I think it was $4K. Since then I've put Ohlins front and rear and have some Driven rearsets on the way so will be into it for about $5K, total. It really all comes down to what you can get the CB donor bike for - if you can find a wrecked one for cheap, you can probably do it for even cheaper than that. $1K for wrecked CB + $1K for swap kit + $2K for Grom. That's not even taking into account selling off the extraneous parts on ebay, etc.
