I do not think you will be sued. Especially if you are making a small game with profits that are too marginal to interest the big companies in the business.
My advice is not proper legal advice and is purely based on history and my experience.
Look at this famous Street Fighter character:
It is well known that it is a parody of characters from SNK and there is a long story behind it yet no lawsuit was ever made. It is very hard to prove a case like this. In your situation where the game I'm guessing is a small indie game, the chances of the 'theft' (inspiration) being detected is unlikely and the chance for it to be reported are even lower. Now think why would they sew someone they cannot make any reasonable profit from for something this ridicules, it will only serve to put them in a bad light.
Here is another example:
Abobo's Big Adventure
This is an indie game based entirely on a stolen character and proud of it.
Another example would be dozens of games with adult content that use famous characters like Peach without proper authorization.
The likelihood of you getting sued before all those people is lower than getting zapped by lighting in a sunny day.
If you are still concerned, apply the old saying: copying from one source is stealing, copying from multiple sources is research.
This is not legal advice. I still think I make some good points. Good luck with your game and choice you make is your own responsibility.
