Hi Lenny,
As an ex-elder, I can say (rather sadly) that if the elder body has already determined that a judicial committee is warranted, they already have enough 'facts' to disfellowship you ... and they are only calling to see if you are repentant. This being the case, moving away will not stop the process as you will be judged as unrepentant, in absentia. However, turning up for one's judicial hearing has often been discusses on this site. And while some chose to go to make a closing statement of some kind (even when they have predetermined to leave anyway), it never changes the outcome.
While the choice is of course yours, all of us here recommend people to first and foremost protect their mental and emotional health ... and whatever happens or choice you make ... you are always welcome to talk things through here.
