Light tanks will come more into prominence in the near future, b/c of mobility issues with MBTs in certain situations, especially with regards to transport and fighting in difficult mountainous terrain, as well as the changing battlefield, there is a reason the M10 Booker was built, and its not b/c the US doesn't have enough M1 Abrams or anything like that. The War in Ukraine has shown the benefits of a Light Tank. Especially with its mobility and its role as an assault gun.
Germany embargoed the Altay and killed its production, Belgium can possibly do the same. I'm not too worried about the engine and transmission b/c I think BMC will be able to handle the task or they might already have an engine in the category to plug in.
The Main issue is the Turret, I think its worth pursuing, even the Israelis have invested in creating their own Elbit 105mm gun, so its not necessarily a niche item, as they also seem to be watching the developments. I was going to mention Leonardo as an option as its less likely to be embargoed as the Italians have a better relationship with Turkey. and I'm happy to see that they seem to have Integrated the turret on the Tulpar.
