I'd be a bit disappointed that the bike shop didn't pursue an alternative like this as I'd guess this wouldn't be the only situation like this they've come across. They could make some customers very happy.
Probably a smaller or boutique bike shop might, but we go to a large chain, where the mechanics at our local store happen to be great on the tools. But they are constantly under the pump, so just don't have the bandwidth to do anything like look at alternatives. They did ask Blue Shark about fitting Fox 32 fork seals on the Bombers, but apparently no go.
