You didn't say what dependency problem you're seeing. Is it python3.6 depending on python3-distutils? If it is, you might try building the 3.6.5-3 source package from sid rather than the 3.6.5~rc1-1 package from buster, as that dependency has been removed there. That should give you a working Python 3.6, but without distutils which has recently been moved to the python3-stdlib-extensions package. If you need distutils you might try backporting that too.
Upgrade the python system from 3.5 to 3.6 might breaks some python system libraries, no ?
So long as it's just the binaries from the python3.6 source package, they should install in parallel and cause no trouble (it would be like installing the python3.7 packages in Buster today, which would go in parallel to 3.6). I think rebuilding python3-stdlib-extensions would be OK too if done with enough care; it would need persuading to build packages including libraries for both 3.5 and 3.6. But yes, that's more risky as it means replacing Stretch packages rather than just adding new ones. -M-
