As proof of "pluggable parsers" working, keep the current

If migration to 6.x implies both a change of the language and an
engine with considerable changes in it, I fear that the decision
between staying with 5.x and upgrading to 6.x will be lopsided.
Not having to suffer from both would mitigate this.
We will definitely provide a
drl5.5 translator. I'm reluctant to do a
5.5 executable parser, because we'll have to maintain it indefinitely;
and all the cost that is involved with this. And also restructuring of
all our test frameworks to ensure both 5.5 and 6.0 continue to be tested.
I'm not say that we won't do a 5.5 executable parser, when the time
comes it's open for debate. I'm just very apprehensive about it. Let's
leave this discussion until the time is relevant, we can start a new
thread on it then.
Either way I'd definitely encourage your work (and others if they want
to do their own language) as independant language efforts.
