Elasticsearch5 alpha5 and NEST5 alpha3

Does anyone here have experience using NEST-5.0.0-alpha3 with Elasticsearch-5-alpha5?

We're currently running alpha2 in our development environment (having some bug issues that should be resolved) but we're hesitant to upgrade because the NEST client doesn't match elasticsearch in version number.

Are any of you successfully running ES alpha5 with NEST alpha3 client?
