20 word shares

[intek71]

Hi, would it be possible to split/recombine into 20 word shares: Trezor T and Keystome offer Shamir backup options, where they split into n/m shares of 20 words. And they are compatible. Still, my concerb is if both trzor and Keystone stop working, I would not be able to recover from my Shamir 20 word share they generate. I am wondering if you could adjust the number of words per share into 20 and that way I would be able to software recombine them if needed. Thank you in advance
