Default Risks involved using a 441 line TV on 625 ?

Good day Gentlemen,

A French vintage TV collector is planning on alternate use of an Aurora SCRF819E converter from its initial purpose : converting 625 to 819 with RF modulation.

The Aurora can be used in bypass mode, ie 625 video is passed on directly to the RF mod without standards conversion. Channel 1 is on 42 & 46 MHz, the original Paris pre-war frequency.

Question: What are the risks involved (if any) asking the TV's H section to run at 625 vs 441 ?
I presume so far that the TVs have line-derived EHT and not the Flyback type.

If a flyback; dangerous to the LOPT ?

I am waiting for the precise TV receiver models.
Will update when known.

Thank you! in advance for comments & suggestions,

Best Regards
