can i change this? instead of creating new..
Is there a reason you don't want to use segwit ?
Segwit introduced quite a few advantages (such as smaller size of transactions which result in lower fees).
It doesn't only help you to save on fees, it also reduces the complete network load, which results in a more healthy network.
Additionally it paves the way to HTLC's (basically lightning network).
It has also things fixed (e.g. transaction malleability) compared to the legacy format.
I can't think of a single reason to not use bech32 (segwit,
ḅc1.. addresses).
