Fiddly dual WAN setup

I have one 70mb fibre WAN connection with bonded failover to 4G that is not as reliable as it should be. We have a bunch of VPN/RDP users who need a reliable line and a known IP to get in. Currently when the failover works, about 2 mins after losing connection, the backup is fully functional. Sometimes we get to 10 minutes and everyone freaks out. We've had much longer outages. Failback is seamless after about 15-20 mins.
Failover with Dynamic DNS is nowhere near fast enough. These users need to be able to reconnect on the same IP with no fuss.
I'm considering adding a second similar speed (but metered) connection with a different provider to fulfil several purposes:
- Last resort backup for VPN connection with a static IP. This should be always available, ie. not cut off when the main WAN resumes.
- Failover WAN for general download (ie. the meter doesn't get hammered unless really necessary).
- Load balanced WAN for upload (ie. doubles upload capacity)
- Dedicated WAN for VOIP VLAN (It's effectively a private link to a VOIP company, and this gets around PCI restrictions on VOIP)
Does this sound do-able? Can you give me some pointers as to how I would configure it?
