This will kill Bitcoin as a currency. Everyone hodl and nobody using Bitcoin. The store of value must be the secondary consideration for Bitcoin, because the value of the currency is also linked to it's use as a payment method. In that scenario it would act like gold.
I'd go for the other way around myself. Once something is a viable store of value, then it can start to become a currency.
Right now one of the reasons people don't want to use BTC is because they've no idea whether their value will be preserved. Because it's gone down, those who own it aren't spending.
Those who buy it to spend it instantly aren't using it as a currency. It's a transaction medium like visa.
I do not see it that way. The big advantage Bitcoin has over it's competitors / Alt coins is the huge merchant network it has built up over the last 6 or so years. Without this network accepting Bitcoin as a payment method, Bitcoin would have been useless as a currency.
We do not give enough attention to this network, and if it stops supporting Bitcoin, we would see a massive drop in it's value. There is no use in storing coins, if there is no place to spend it.
