Do not do it or you will regret doing it. No wallet is a 100% safe therefore do not put all your hopes in just one wallet as it might fail you sometimes.
Tbh, in 99.99% of the cases problem is not a hardware wallet but instead a human factor so having more wallets won't mean much if you don't know how to safely store them.
I personally have only one hardware wallet but I read some good arguments here why its not a bad idea to have at least one more.
