Crossbracing on Floor Joists

I am considering installing underfloor radiant heating in my kitchen and master bath to eliminate COLD tile floors. Access under the floor locations is via the currently unfinished basement. One of the products I am considering, HeatWeave WarmWire from, requires the heat wires be installed 2 inches BELOW the subfloor. There are 2x4 crossbraces between the engineered joists that are in the way. Can these crossbraces be removed to make the heat wire installation easier and then re-installed BELOW the heat wire without compromising the floor? This means that the crossbracing will no longer go from the top of one joist to the bottom of the adjacent joist but from about 2 1/2 inches below the top of the joist to the bottom of the adjacent one.

If it was solid lumber framing, my OPINION would be go for it. Since you have engineered joists, you'd have to ask an engineer, preferably the one that stamped the plans in the first place...if not, then resubmit plans with changes (loss of cross-bracing) to the new engineer for another stamp. If you do end up taking them out and can't put them back in from the top of one joist to the bottom of the next, there's no reason to put them back at all.

Reinstall new bracing

Remove the old cross bracing. Then cut 14 1/2" - 2" x 8" for 10" joists or 2" X 10" for 12" joists and install these as close in a row sideways, flush with the bottom of the joists.
Space them at the same(approximate) intervals/staggered as the cross bracing had been, to accomodate nailing(16 penny's) or toe nail them using 10 penny's with an air nailer.
