I had a brief time where I had a Cello. I know that knowing how to play violin helped me play the cello. For some reason reading the Cello music was easier for me that VIOLA..... Anyway... I know this doesn't answer whether it will screw up your violin playing.
I was a beginner violinist (still am in a way) when I got the cello so there wasn't anything to mess up.
I loved the Cello.. I regret selling my Cello. I loved it and it was soOOOOO much more forgiving than my violin.
So can I ask... did you get a cello?
Have a great day.
