The person in the OP's scenario does not suffer from impotence. It is impotence that is a canonical impediment to marriage. In this situation they have the ability **to consummate. Choosing not to consummate does not invalidate marriage. A non consummated marriage is **valid, but not indissoluable. It can be dissolved by the Pope.
I understand the OP is not impotent - I was drawing a parallel. The ability to consummate is only there if the other spouse is willing to a) risk his/her life and the life of future children most likely leaving them parentless and/or b) not be open to life in the marriage or c) enter a Josephite marriage.
In the case of a Josephite marriage I would think there would be an issue created by the fact that the marriage can only stay unconssumated as long as both spouses are in agreement to this.
I think there are many complications to this Canonically and it should be discussed with a priest or possibly someone very well versed in Canon Law but not on an internet forum.
