You can crosstrain in anything. Some styles/theories/training methods are discordant but you can evaluate them and adapt what you want out of the experience.
What matters is that you develop a fighting system out of fighting experience, not what somebody else claims is good. If it's an exercise system you want, create one that works for you.
If it's artistic preservation you want, stay with one system and plumb the depths. That's when "style" matters.
