CA Non-Compliant Danielson FTC Square trap mods

So based on my read of the current CA regs, there are two issues with the relatively inexpensive Danielson FTC 24x24 folding traps:

1) escape opening created when rot cord fails is not at least 5" in diameter
2) the cotton rot cord holding the escape ring over the escape opening is 4 pieces, rather than "a single strand" (sic).

If so, both problems would be solved by cutting an opening in the top greater than 5"x 5", adding a hinged door lid of PVC wire mesh, and using appropriate cotton rot line with the bungee for the fastener for the lid. (Basically like the top-loading door of the similar, but CA compliant, Promar TR-555). (And then permanently affixing the escape ring by replacing the cotton with zip ties or stainless wire).

Does that sound right to everyone, or am I missing some other deficiency?

(I know that one can also bend the corners of the escape port to make a 5" opening and threading a single piece of cotton rot cord around the perimeter of the escape ring. But I like the doors on the Promars, and I have access to wire mesh to make lids).

I just made one of the sides the escape hatch. On one side I folded down the hook and cut off a bit at the end so it cannot catch the top. I used an elastic tie down attached to the top with a single cotton line to hold the wall up. See pics.

Thanks. That looks legit to me.

I also have an older Danielson Alaska model, where, as it came new, one of the side pieces doesn't have the J hook bits on the top edge and that side is held closed with a single piece of cotton rot cord woven along that top edge. So like yours, the side panel will fall open if the cotton rots out. (That one also came with one of the escape rings tied on with cotton).
