I've been in this position and it didn't go well. Definitely avoid this scenario in the future. You can ask but I wouldn't be too optimistic and the conversation may not go well and impact your relationship with your employer.
A long time ago I owned the domain name saintlouis.com and had started a site that somehow eventually came under the wing of my employer. Needless to say I didn't own the saintlouis.com domain when I left not long after.
