I expect that the chainline will be more than ample, so not expecting this scenario to be problematic at all.

But, as nlerner says, test fit the cranks for clearance and for the front derailer's ability to retract far enough inward for robust downshifting (expecting all to be fine).

I've used alternate, off-branded bb's for Stronlight crankset installs in some cases, to narrow up the installed width on the drive-side, so I don't think that your drive-side spindle protrusion will fall short.
