I don't think the e-collar will produce the results you want. Basically, it looks like the problem is stress. The collar would cause even higher levels of stress. While you may curtail negative behavior in the short term, you're setting yourself up for an explosion of fury. It think you've already seen this with the prong collar.
Overall, I think that finding ways to reduce stress in the home will be the key to improvement. You can use positive methods to help the two dogs get along better, once the stress level is lowered. I'm greeting the impression that things are tense right now. The dogs will pick up on that and act accordingly.
I suppose having the mastiff fixed is off the table as well?
