Linear OT mapping across different spaces

[j-bac]

🚀 Feature

Would it be possible to perform linear domain adaptation (like is done by ot.da.LinearTransport) but across different spaces ?

Motivation

The LinearTransport is very useful to align distributions without losing information from the original geometry. It would be great to have the same feature but for distributions in different spaces / in the Gromov-Wasserstein context
