Do these names sound ridiculous together? Tilly Lumen?

I need help!
What do you think of this combination - [name_f]Tilly[/name_f] Lumen.

Is it too L-heavy? Or do they work together? I can’t decide if it’s really beautiful, or awkward and pretentious. Your thoughts?

The flow is a little L heavy. It might not be so bad if the middle name had L’s in the middle rather than up front. Personally I’m not fond of Lumen as it makes me think of the lumen of a blood vessel.

Too L-heavy for my taste, sorry.

I also think it’s too L heavy, I’m afraid.

I like combos that are slightly l heavy, but I find this to be too much
[name_f]Matilda[/name_f] Lumen would sound fine

Not a fan of Lumen. [name_f]Tilly[/name_f] is lovely

I agree that [name_f]Matilda[/name_f] Lumen works, with the nickname [name_f]Tilly[/name_f], but [name_f]Tilly[/name_f] Lumen is too L-heavy for me, too.

I agree that [name_f]Tilly[/name_f] Lumen sounds awkwardly L-heavy. I love the suggestion of [name_f]Matilda[/name_f] Lumen.
