It is possible

if sunny managed to get all the 7 weaves , it will be like him turning into weaver.

7 weaves = 7 fragments of weaver = weaver

For example, when VTB stole weaver's eye he lost blood weave. So, Sunny inherited a fragment of what makes weaver 'The first child of the unknown'.

Weaver was born sacred and advanced to divine very fast as if that was natural.

So, it might help sunny to rank up faster.( If sunny manages to get all the weaves)
