For real

OP is literally churning, just to a different wallet if his.

If transactions aren’t completely swept and they keep a non-zero change output, it makes things worse

Churning is fine if you have coin control and keep note of your outputs

Different wallets are fine if you manage to keep track of everything and properly sweep outputs. Avoid spending multiple churned outputs together if you can to prevent linking them together, but apart from that, it’s good.
