Honest, totally unqualified opinion?
I really don't think so.
The reasons you suggested, I think are very accurate.
The shape of the stands are all wrong. The rake (angle) of the seating as they go up & down, is all wrong. The distance of the majority of the seats from the pitch, is all wrong.
Trying to fart about, making changes to what is there, imo, would just be a complete waste of time & money which I believe would hardly achieve anything for anyone.
I only want one of two options:
Knock the whole thing down & start again,
or
Move again.
We don't get our club 'back', until one of those two things happens.
Anything else would be just further taking the piss out of us.
Which is why, G,S & B, have to go, because they ain't ever going to do either.
And that's not even mentioning the travesty of making us leave Upton Park.
