This sounds like something that's already achievable:

#my_element {
     width: 50px;
     height: 50px;
     opacity: 0.2;
     transition: width 1s 1s, height 1s, opacity 0.5s;
}

#my_element:hover {
     width: 100px;
     height: 100px;
     opacity: 1;
     transition: width 1s, height 1s 1s, opacity 0.5s 1.5s;
}

Transition properties are taken from the "to" state:  
http://dev.w3.org/csswg/css-transitions/#starting

This also works for properties whose values can't be ordered (like  
'color', 'background-position' and 'transform').
