gl > gr attested in Romance?

Hi!

Is the sound shift /gl/ > /gr/ and/or /kl/ > /kr/ attested in Romance?

Or at least, would you think it's feasible like the /bl/ > /br/ in
pt. 'branco' < BLANCU(M)?

I am thinking about 'grorie' < GLORIA(M) in a new toy romlang I
started yesterday.

Also, what about /Nn/ > /Ngr/ like /mn/ > /mbr/ (sp. 'nombre' < NOM(I)NE(M))?

Tere, I'm thinking of 'ringre' < RE:GNU(M).

Bye,
  Henrik
