Alternative finger positions

I have been learning on a high D whistle and just for a change I bought a Bb and instantly found a little problem with the finger holes in that I can’t easily get my right hand ring finger on the lowest hole due to arthritis. So far I have got round it by taping my ring finger and little fingers together and playing normally, this makes my little finger automatically cover the tone hole even though I am ‘driving’ with my ring finger, it’s not perfect but I’m hoping I’ll get used to it.

Anyone else had to do something like this with the bigger whistles?

I’ve not seen taping fingers together, but I’ve seen people play Low Whistles using the little finger for Hole 6, the ring finger staying on the whistle as an “anchor” finger.
