Not your typical Wings..

I have been trying to sketch an idea for a tattoo that I saw while I was dreaming, and I am having some trouble. Both of my grandmothers are in some medical trouble and I just found out that one of them has less then a year to live because of a brain tumor, and the other was diagnosed with diabetes (she is already anemic, cant really eat anything, and recently fell down my steps while visiting and broke her pelvis, and had a stroke). I have been wanting to get two different tattoos that represent that they are always going to be my angels, alive or in heaven. I want either one of two things.
One: I would like to have wings that look similar to clouds? and the initials LFB (F being a little bigger becasue its her last name) and the other to be MTT (with the center t being a little bigger).
Two: a cloud of somesort with the same initials resting on it.
PLEASE HELP! I want to get these soon to show each of my grandmothers that they are my angels!
Thanks.
