Hi Yugant...no PM seen?
As for top plates, yes pier plates do make nice stuff but they are mainly intended for concrete piers, thus have the colloquial "rats cage" for alt/Az adjustment (thought theirs is nicely made and designed). Even if you have a concrete pier all you need, for the G11, is a round top plate and on top of this a Losmandy MA adaptor that bolts to the plate (can probably even do without top plate).
The MA adapter can thus be rotated for Az for rough adjustment then use micro Az adjusters as required. As for Alt, well as long as you pier top is ~+/-15 degrees or so it doesn't matter as thus can be adjusted out by the mounts latitude or Alt micro adjuster.
Absolutely no need for a set of adjustable pier plates in this situation. Thus my pier has none, just bolt MA adapter on top rotate to suit!
edit:
ahh just got an email.
In reply, pretty much what I said above. If you do a concrete pier just use a top plate of any old metal (bolted to the pier) and on this mount an MA adapter so it bolts thru it's centre to this top plate. No need for precision in Alt/Az for above reasons. Rotate the MA to find SCP then drill/tap some more bolts to hold the MA secure although it's centre bolt should be enough.
