2025: is there a good TTRPG system to run a Mobile Suit Gundam game?

I've asked this question before and I've done the research on this Reddit and more further afield, but I guess I'm looking for new perspectives:

I really want to run a campaign set in the Gundam IP. I'm not sure whether I specifically want to set it in a Universal Century AU or make my own twist on the themes and motifs of the series, but I do want it to be *Gundam* as opposed to a different mecha system e.g. Lancer.

I want it to be a fairly tactical game in terms of builds, combat options, positioning etc.

I've tested Mecha Hack and it works *fine*, and I'm tempted to homebrew it together with some of the more narrative Gundam-inspired systems like Beam Saber.

Or maybe something like Armour Astir, adapted to Gundam. But I do want it to be moderately crunchy. Not super-crunchy (which has lead to me writing off Mekton, after consideration), I consider something like D&D 5e moderate.

I'm desperate to figure this out as I ideally want to run this after my Alien RPG campaign finishes in 3-6 months, but I'm still down a system or systems that could make it work really well.
