I dont think so,

1. I dont think the idea of not being able to shield would go down very well with the kind of players who have shot down the notion of 'cool down periods ' for reshielding. 

Some towns? Which towns and when?When logged off, when sleeping, so you dont know about it? 

Plus theres already a work around for having no shield, so what would be its purpose?

2.Of course theres little interest in the gold tiles, its far to slow and gold has been devalued. There is currently little need to yield gold, its a waste of a march

The gold rush  competition was a non starter at least for me,probably others too, beause it was impossible to get even the first level, even playing solidly for the whole time it ran.

However, you never know,even if it isnt exactly as you suggested it may give a hint or come back in some other form, because ages ago someone suggested a reward for gem fusing, which at the time seemed ridiculous.
