Sounds good to me.
The moot point is mastering your technique/form. As T and Hendrik have already stated (my god! They're agreeing! Watch the skies!) in the main traditionally this is against the principles of resistance training. However, just as I think it's easy enough to cross train without confusing principles as long as you're not a moron, I also think it's easy enough (and much better) to lift weights AND keep to your traditional training. I think of it like this: if I miss my perfect wing chun punch or JJ takedown or whatever, I can just rely on brute force and ignorance!
