Payment gateway requires configurable parameter for display value in checkout

We need localisable names for PG when we select them at the payment stage of the checkout.
There are two ways IMHO that we can achieve this:
1. Use displayValue parameter (same way as we have for attribute displayable values) and create either Localisable Failover Model. However this will require some knowledge of the value delimiter which may be not very user friendly
2. Create display value attribute per locale (e.g. Product Descriptions)

Can we fit this in for v2 - seems like this is an important feature that we missed.
