Mixing tube brands

I want to mix Two Gold Lion two KT-88 tubes and two Psvane KT-88 tubes to blend the sound. Is this a problem?

With power tubes, you can swap different brands of the same tube. (For example, 6L6 tubes from different manufacturers.) But do not swap different types of power tubes unless you are absolutely sure you know what you are doing — damage may result.

If you can't do that don't try. Even then I wouldn't do it. Personally speaking I generally select matched power tubes of my choice based on SQ (not so much power ratings) and make more subtle changes to their tone by selection of small tubes.
