I have designed a Fiberglass Cymbals and have mounted two triggers (one at the rim and the other at the bow) but when I hit anywhere I get one sound dont know how to get distinguished trigger sounds... should I tweak the crosstalk / xtalk or use a Keith rapper circuit? or any other mods...
Any help would be appreciated...

I don't think you can really separate two zones with such a design - too much of mechanical crosstalk between two piezos.

Viewing your pics, you've stuck one piezo on bell and one on bow (near the edge), I think this configuration should give you better results (but it will be one bell sound and one bow sound, good for ride but not for crash).
What is impossible to achieve with tow piezos is distinguish bow and edge triggering (even with a keith rapper circuit), but bell and bow should be doable, and I think this is what Roland make with the CY-13 which use one piezo for bow and one piezo for bell.

Check if the Megadrum bell (or bow) input is set to dual piezo, try to increase the gain and /or threshold of the sound your not able to trigger, and see what happen.
Crosstalk should not help since the dual piezo is set, dmitri can maybe confirm, I'm not 100% sure.

I don't think separation between bell and bow with this design is doable, no mater what settings you use.
Even if CY-13 uses 2 piezos for bow and bell, I guess its design implements some mechanical separation between two zones.
But you can try to configure your cymbal as dual zone and prove me wrong.

And Sylv1co is right, crosstalk settings have nothing to do with zones separation in dual zone pads/cymbals.

but when I hit anywhere I get one sound

It's still sound a bit strange to me, you should at least get sometimes one sound, sometime another...
Have anyone have any idea on how Alesis Surge or Field Electronic drum can get three zone with their metal "one piece" cymbal ? I'm curious, I thought they use a piezo under the bell and maybe a switch on the edge... Any idea ?

He should...provided at least DualHead, HighLevel on both Head and Rim (which is the bell in this case) and DualMidPoint were properly configured.

That is my experience with diy dual piezo cymbals. You must find proper settings for DualHead, HighLevel and DualMidPoint as Dmitri said.
