The design and analysis of trusses is very complex and unless a professional engineer has provided the alteration design for you, you are likely to create a safety and liability hazard for yourself and all subsequent owners of the property.
The zoning laws of you're community might even prohibit making that kind of alteration without a PE design. Ask your Building Inspector.
NO contractor or carpenter is knowledgeable enough to know how trusses are designed unless he is a drop out from the structural engineering profession..
Any fool can use a saw and hammer and butcher the structure and say it was (physically) easy, but it may be a time bomb waiting to collapse.
Don't take this lightly. There are lawyers standing in line just waiting for this opportunity.

i have scene plenty of engineers screw things up.... just because its drawn on paper doesn't mean it always works, and you dont have to be an engineer to modify a simple roof truss, just have some common sense,
think a fabricator designed the new fords so that when it needed a head gasket you had to remove the cab? doubt it
