The OP already seems to be spending an hour on BART to/from SFO. Substitute a 90 minute heavy rail ride for that. At the SMF end, add a ~20 minute ride on the once hourly 142 bus and a 2000 foot walk between bus stop* and train platform.
Agreed that this isn't practical for regular use, but in case SFO and OAK are fogged in, or there are no seats available, SMF could be an alternate.
