Yes, actually. A long quest that you would have to be dedicated to do with someone, really wanting to marry them. For the wedding and gear have them different tiers of cost.
Basic would be something cheap, maybe 10k + doing the quest.
Higher tier plans can get up to 1 mil for the outfits, and 2 mil for the mount (or varying on server economy status).
I think housing prices are ridiculous, but not impossible. A large house was something that I /really/ wanted, and in saving up since 2.38 I was able to get a large personal house to myself in 2.4. I did this singlehandedly, no one helped me gather the gil. It was not impossible. If a single person can raise 60 mil over a few months, I think that two people would be able to reasonably be able to raise 2 mil together if they really wanted to get married.
This is also more fair to people on tight RL budgets.
If we really want both people who have tight in-game budgets and tight-RL budgets, I would really really not mind having both options. You can pay for gold in-game for a high amount of gil (like 2-4 mil) or you can pay for it out of game in the cash shop. It would appease both styles of play.
