That's a good mod and I applaud your effort.... however completely unnecessary. Sorry.
I have personally found between all the Tekno vehicles I run, 1) the wing screws and 2) the rear bulk screws are most prone to bending. That being said, I have never stripped a single one after multiple seaons.
Recommendations: Use chapstick or oil to thread it for the first time. Use a QUALITY driver (I've heard "questionable" feedback on the VPPro brand to say the least) and you're much less likely to have issues. Use a electric driver to initial threading which decreases the likelihood of stripping probably 5-10 fold. Just ensure that if you do that you go SLOW and keep it cool and lubricated in order to not stress the plastic/composite.
While I'm not a losi man for vehicles, I use them as a %#@%#&%(@@&$@ hammer and they still go strong

I replaced my first 2.0mm losi last season bit after roughly 10 years of use finally... I think that speaks for itself.
