LP 12 with 2 arms ?

Hello everybody!

Did you ever see a LP12 tweaked with two arms?
We have 3 kinds of mythic turntables ,Thorens TD 124, Garrard 301 and 401 and our beloved LP12.
We often see the 124 and the Garrard with 2 arms, why not the LP12?

I would love to have a mono cartridge without having to get another TT
(WAF consideration...)

Thanks for yours answers.
