Yeh Casa node (and probably others) do this https://store.casa/lightning-node/. It’s about trust vs. verifying the data yourself, see their entry here: Casa Node Update — January 24, 2019
We’ve now added the option to resync from Casa, which downloads the chain from Casa’s Bitcoin node. This is much faster than syncing from scratch (it takes about half a day), but it does require trusting Casa’s blockchain data. It’s the same level of trust you put in Casa when we presync the node before sending it to you. As always, there is the option to sync from scratch for users who want to verify the entire chain themselves.
There’s also the more practical issue of the cost of hosting something like that as the chain is over 20GB so that soon adds up.
There are also a few topics mentioned in this AMA see Technical AMA w/ Zcash team December 14, 2018 noon PST - #25 by adityapk00 and Technical AMA w/ Zcash team December 14, 2018 noon PST - #30 by adityapk00.
I think best interim step is syncing on a more powerful machine then simply copying the data over.
