The meter could be moved outside the garage and a new W/P service-rated disconnect be placed beside it. Then refeed the old panel and turn it into a sub-panel...isolate neutrals from grounds, etc. I suspect there is gas heat and gas cooking judging from the gas meter and the size of the meter housing so 4-wire feeders to them wouldn't be a problem. Now moving the gas meter outside the garage is a whole new adventure...
