I am new to woodworking, which will probably be readily apparent as you read the below
I've got an 8' craftsman butcher block workbench top that I've had laying around, and I'd like to use it as the top for a woodworking bench: https://www.kmart.com/craftsman-8'-b...p-00914965000P
Two issues:
1. It's 1 3/8" thick - I'd like a thicker top to allow me to use holdfasts
2. I need to figure out a way to attach the top to a base. The workbench will be in a detached garage in Pennsylvania, so will experience significant fluctuations in temperature and humidity.
Questions:
1. How likely am I to run into issues if I face glue a couple of kiln dried Douglas fir 2x12s to the underside to get me the bench top thickness I want? Sears says the top is made of rubberwood/parawood - looks like shrinkage is on the low side: https://www.wood-database.com/rubberwood/
2. What would be the downsides of the below design (view from end of bench, would also have stretchers lengthwise mortised, all stretchers 2x6)? Legs would be 3 laminated 2x6s, with the vertical dotted line indicating the middle 2x6 extending into a cutout in the 2x12. I'd then put dowels through apron/leg/2x12 underside of bench top. Is there a better and/or easier design I could use?

Hope this makes sense, please let me know if unclear. Appreciate any thoughts/suggestions!
