floating floor with joists on their sides?

I'm going to be floating/raising my floor in my writing room mostly for the purpose of running my cables from the desk to the machine room under the floor. Since I'm bothering to do it, I figure I might as well put some neoprene feet or pads on the joists so that they don't touch the slab directly. I would just use the Aurelex U-boats, except that I want to only raise the floor 2", laying the 2x4 joists on their side. Anyone know of a bizzaro U-boat-ish thing that lets me lay my joists on their side?

no one?

A few words from John that you obviously missed the 1st time you read through the stickies- "You will NOT be assisted on this site if you: 1. Don't fill in the Location section in your profile - this is an international site and we need to know what country you are in. 2. Put up a post saying "I have a room X feet x Y feet - what should I do?" 3. Put up a plan that has no dimensions and does not point out pertinent facts like there's a pole in the middle of the room and the right hand wall is all glass. 4. Post pictures greater than 700px wide. 5. Don't explain what you want to do within the studio - how loud you play, what kind of recording setup you have etc. 6. Don't explain how much isolation is needed because of neighbours etc. Please also read the "Don't Post" articles specific to each forum before you post.
