I know what you mean. But consider this:
The fact that the combination of needling and minoxidil works well is because both of them also work well alone, without the other one (we know this based on empirical data). I'd say that to think a topical will work well in combination with needling, at least a condition would be that it works well alone as well, so its effect would be stacked with the effects of needling. Sadly, this does not seem to be the case for Trinov, so there should be better candidates to experiment on, such as rosemary oil (weaker than minoxidil, but arguably stronger than Trinov).
Perhaps you would think that needling will improve Trinov absorbtion so it can reach the follicles more efficiently, but in theory, the Trinov lotion already "solves" that issue with the addition of liposomes, and nevertheless its efficacy for regrowth was minimal in the published study.
The only hope left for Trinov is that somehow, it miraculously works well in the community trial being conducted here in the long term, which would strangely contradict the already published study.
