With respect: licensing can be complex, particularly if one is new to it, and the ramifications of messing-up with a licensing issue like this could result in legal action against yourself / your project, at worst.

If speaking with a lawyer is not practical for you, you will need to be 100% certain that you know what you are doing with all of these different licenses, and fully understand their compatibilities / incompatibilities — or at some point you will very probably get bitten by this.

I'm not sure why you say this route "doesn't work". Because it certainly does — of course you would need to find a lawyer who has good knowledge of software licensing.
