My suggestions is to just make an additional L2 account. Try protonmail.com they let you make tons of email accounts.
The Valakas necklace isn't a big deal for a buffer, it's really not needed. Make a new PP on a new account and use it to buff your scav as your main hunter. BTW -- Scavenger really won't make you extra money though, you will be dissapointed).
Finally, you are going to want Vampiric Rage so I suggest make a DE mystic buffer on yet another account for that buff. They can also cast recharge which is nice.
In total you would have Scav account, PP account, and SE account. And whatever accounts you alrady have that you haven't mentioned...
