Is egpu future-proofing valid for a TB5 laptop? How about TB5 egpu with TB4 host?

Been considering a workstation laptop because gaming aside, it does most non-performance things better and it's probably got a leg up reliability-wise. However, it does get stuck with an RTX 5060, which has a double whammy of being power limited in this particular device and nvidia doing their 8gb vram shenanigans. For personal preference and space reasons, I'd rather not build a separate desktop.

Now we're still at the point where I could probably do like 95% of titles at respectable settings (forgoing some of the bells and whistles, which is fine) and get 1080p 60fps, which is very acceptable by my standards. But my understanding is that it's on the precipice of viable for more demanding titles, even with compromises on settings. This laptop is TB5 equipped, one would think that egpu at least can solve the vram issue and push resolution or settings up a bit to get 60fps where the dgpu would otherwise be unable.

Caveats:

Unless I get a 50 series card, I'll have to go AMD to avoid drivers freaking out, and fwiw, nvidia does seem to have the most going for it feature-wise. Some games really didn't like TB3/TB4, might expect some inconsistencies with TB5 as well. Even with the more generous bandwidth of TB5, internal screen might still be dicey, which half defeats the purpose since keyboard/screen is a big reason I'd get the thing.

Not quite sure if I just need to rip the bandaid off and get a gaming laptop to avoid future grief, or whether TB5 has shown enough to be relied on in the future for "good" even if not the "best" gaming.
