Could these trees cope with pollarding?

[Boybeck]

Hi there,

 

I have an elm and four field maples which appear to have formed a hedge at one time. I would like them reduced in height by a tree surgeon. If they are pollarded to the height of the trellis in the attached pictures, would they bounce back or would it spoil them?

 

Many thanks,

2 or 3 meters above the trellis height might be a better option unless that's out of the question?
