I-Hsin George blooms on the second spike

I now have a big urge to put its pollen on bellina that I posted couple days ago. Should I? I know that the cross of I-Hsin George and bellina is registered but could not find pictures of its blooms, so I cannot justify if it is worth to spoil bellina bloom that I enjoy so much.
