lowRISC are currently on v0.4 of their design, and we're already half way through the year. I'd be very surprised if they decided to commit to building an ASIC before they reached v1.0.
By the way, I'm not trying to stop you dreaming, I'm hinting the fact that if you want to speed things along you should get involved in the embedded space. If you're waiting as a passive consumer you'll more than likely get disappointed, but if you're actively contributing to the platform you may find the wait more bearable as you're helping to speed it along.
