Tdlr: Poison and Disease rules are broken atm, houserule those rather than swapping character.
I know this is not the direction you were looking at, but my suggestion would be to have your table revisit poison/disease rules and heavily Houserule how they are handled. Among other things the speed of healing so your character can be back in action faster.
In the current state of the rules, they are extremely debilitating and can really suck the fun and rhythm out of the game (there have been a few threads on them here these past weeks). Plus the options to heal them at low level are close to non-existent. The speed at which tiers of infection are lost should be sped up and more options for removing them are needed.
In our case we have a player (toon is a Technomancer) with maxed Medicine, all kinds of medicinal items on her and the "Medical Expert" Feat. When our Envoy got poisoned by the same critters that got you in the jungle (and then got poisoned again later by a much worse poisonous creature) the DM and her were looking everywhere in the rules for options to heal that poison and not have us need to spend 24 hours until the Envoy could move and 72 hours before he would not be utterly useless anymore. They found nothing. I think in the end they agreed that the "Medical Expert" Feat gave her access to an action to treat poison (DC 20) that uses a dose of Antitoxin and immediately removes a tier of poison and that is usable once per day per patient (or something like that). Not saying it's the best solution, but RAW is pretty awful for low levels as is.
Hope this helps a bit!
