One of the nice things about the velious sentinel plate suits is it is absolutely loaded with +int and +MR. Especially for low levels where the returns on stamina aren’t that great, it’s a big boon to the other lower int sk races. Even though you already have high int, look into it. AC is decent and you can usually grab a full visible (matching) set for as low as 1-1.5k.

All in all I like your plan.
One thing I’d encourage you to focus on is finding and prioritizing str gear for the low levels. Having low str on a plate class is a huge quality of life hassle for the low levels.
