Thanks Dale and Lorraine!
I can adjust ducting sizes to match, I found some great 10" inlines on Grainger's site and I was planning on running the makeup air under the bench (both to minimize the outside cold and flu-reversal) but I'll consider my other options regarding the alley for makeup air - I do have a small window behind me but it's not an ideal location.
Regarding insurance policies - propane storage in the alley is legal, pretty much every house on the block has an alley and tucks their grills back there. My insurance agent said everything sounds fine as long as
1) no negligence in design/execution (follow all building/safety codes but there is nothing that says I CANNOT operate a gas-powered torch in a basement studio, at least in my 'hood which is zoned for both commercial and residential)
2) I'm not operating it as a business, else I would need an "umbrella" policy.
