I think before any proposal could be made for altering the inflation schedule an analysis of the current schedule could be carried out what was the reasoning
The schedule was based on non-merged mining which requires creating enough incentive for miners to mine enough to secure the coin. That dynamic changed significantly with merged mining because the coin will be mined anyway, even with a small mining schedule (e.g. doge) because whatever subsidy is still free money to the miner as they dont have to expend any extra resources to merge mine an infinite number of coins.
