Raises in the BTC price may diminish the halving impact. If the BTC price doubles, then the halving is totally mitigated.
However, that doesn’t count for the last halving, when subsidy disappear as a whole, independent on BTC price.
BTC price also doesn’t help with raising the revenue. We should expect that, with BTC valuation, fees should fall, if the willingness of the users to spend value in tx fees stay the same. I mean, the raise in BTC price may value the revenue from yesterday if it was stored in BTC though.
