I've looked at 3 piece cranks options for the cartridge bearings upgrade. If the spindles match I have some old XT and Dura-Ace cranks around here somewhere but either of those might look odd. The Isla Vista needs a new handlebar stem as it now has a groove cut into it (4.5 inch grinder slipped while cutting out a rusted/seized clamp bolt, lol). That'll be the first lighter replacement component. Thanks for the tips.

Yesterday I did the BB and front hub on a neighbor's Felt Bixby cruiser. New bearings, marine grease, etc.. It has a Nexus Internal 3 speed rear hub. That'll have to wait for another day or a better mechanic unless the Shimano Internal Hub Grease he's ordering resolves the odd friction sound it makes when freewheeling. That's a cool grease port Shimano designed for the Nexus 3 w/Coaster brake. Felt makes a nice cruiser.
