Thinking of having my knights redone. Thoughts?

So I commissioned them over 10 years ago to a studio that didn’t exist anymore. I have 5 big knights and 2 halverins. There’s a resin atrapos and magara and 3 magnetised 1st gen knight (pre Preceptor) knights.

I love how they look but they are starting to show their age as parts falling off, scratched paint and also being so constrained with no big knights, almost no armigers and limited FW knights.

What do people think would be the best options.

Have a Canis Rex painted in traditional style for more options?

Pick up the FW stuff and get matching paint or something different?

Go into the little guys, say 4 of each type and make them a the base of a new army with the same or a new paint scheme?
