Doing these things like they used to do it in the small shtetel inderheim is what everyone yearns and wishes, but will very unlikely happen.
I highly doubt weddings will return to anywhere near their prior size at least through the end of 2020 and probably longer, given residual social distancing efforts.
I assume a gradual easing of social distancing over the coming year (minyanim resume by the summer with certain density constraints, schools resume in September etc), but that there is no handshaking, no tight crowds, no hand-in-hand dancing, mask wearing in public, etc. at least into 2021.
At that point the norms will have been effectively disrupted and there is a realistic option for this communal behavior to permanently reset . . . . . . providing there is a genuine will and concerted effort from both those who can and cannot comfortably afford these expenses. (BTW - There are many affluent families signed on to that simchinitiative.org list).
One might even argue that remedying this is among highest forms of tzedoko/chesed as it maintains the dignity of the beneficiary (more dignified than offering loans or grants for hachnosos kallah so that every family can keep up).
