Integration of new test case reducers?

I've seen that the project uses separate minimizers for different input formats (like JS and HTML) and also supports a syntax-unaware reduction approach, too.
My question is whether the community is interested in the integration of a general solution for these tasks which can work on any kind of formats?

In the last few years, we've developed and used two Python{2,3}-based tools for this purpose:
1) picire is a syntax-unaware parallel minimizer that can work at line or character level
https://github.com/renatahodovan/picire
2) picireny is a syntax-aware parallel minimizer (built upon the previous tool) that can reduce any input formats that have ANTLRv4 grammars.

Available grammars: https://github.com/antlr/grammars-v4/

I'm happy to work/collaborate on their integration if there is any interest in them.
