Using datacenter + 4G proxy on same account twice

What do you think about using datacenter proxies for F/UF, Comment, Story Viewing, Likes
& using 4G Proxies only for reposting on the same account?
Could you use maybe 100 accounts and more on a single 4G proxy only for reposting?

Each account would use the proxy for 2 - 3 times a day.
But the rest of the actions would be with ipv4 proxies (datacenter - 1 account per proxy)

If they are from the same zone : risky
If they are from different zones : more risky

I've done it but only with a rotating IP4 LTE mobile

good idea in theory, but is that natural? human?
