I find this role a bit underpowered (just a first opinion) compared to other Mafia roles. Let's assume you choose a dead Townie as your disguise target: There is little reason to pick anyone except a Town target. Even Survivors and Amnesiacs may be lynched or executed for safety reasons.
 * Pro: If the Sheriff interrogates you, you appear to be not guilty.
 * Same as other Mafia: If the Investigator visits you, some of your possible roles will be Town, some Neutral, some Mafia.
 * Con: Compared to your other Mafia members, you cannot roleblock/blackmail/listen/clean/forge/frame/investigate.

Your most effective uses are: I believe the main issue with the idea is that you have little possibility to actively help your team - your ability focuses on protecting your identity from the Sheriff. At most, you can pretend to be a Town member and try to influence the day chat.
 * Disguise yourself as a target who was cleaned. You can be sure that nobody (except another evil or the informed Medium) will counter your claim and you are protected from the Investigator and the Sheriff. Con: You still don't have a usable ability.
 * Disguise yourself as a dead Sheriff or Vampire Hunter. These are the only Town roles which do not have Mafia alternatives for the Investigator.
 * If the Mafia Deception is confirmed, disguise yourself as a Lookout/Medium/Retri. The Investigator alternatives are Forger/Janitor - if everyone knows there is neither of them, you are safe from the Invest.
 * See above, but for the Mafia Support.
