I decided to do this after I installed amber sidemarkers.
Overall I like the new look, but even with careful hands, I managed to get 1 crack on the driver side and 2 on the passenger.
I just sealed it up from the inside, plus the eye lids helps hide the crack and sealant.
Here's the steps, sorry no photos of the process, just finished results.
1.
Bake both corners in the oven at 200F for 10-15 minutes.
2.
I used a hobby/craft/model knife, like this one:

I used 2 knives, the tip will dull/chip. Plus these knives are cheap.
to pry the lens open by placing the tip between where the lens meets the housing.
Doing so, slowly tap with the handle of a screwdriver until the glue breaks contact.
Work from the bottom/sides first, the top is harder to pry as it has a lip that conceals, but take your time and it'll break loose.
Also when prying, careful not to scratch the silver/chrome finish, it will flake into small pieces, not good.
I won't guarantee it wont crack, but if you keep the pressure light, the crack will be minimal in size. Take time.
Forgot to add, A flathead screwdriver can aid the prying process in conjunction with the knife.
3.
Once you have the lens off, pry off the amber reflector.
From here you can either seal the lens back on using clear silicon adhesive
and be done of it follow STEP 7 below.
Or like I did, used silver reflective tape to create a clear reflector.
If you're gonna make the silver reflector, I suggest you seal up any lens cracks,
so that the lens will be ready by the time you finish making the reflectors.
Silver Reflector:
I used this reflective tape:

I used two rolls, since I made mistakes...lol
It has a peel-off backing, so it enabled be to lay it out to make the shape
then I can just stick it onto the same spot where the old ones were.
4.
To make the silver reflector, trace one of the amber reflector on the front of a piece of white paper. On the backside of that paper,
outline the trace since it'll be the guide line to cut.
5.
Now lay out the reflective tape on the correct side of the trace.
Use masking tape to hold it in place as you lay down the reflective tape.
Basically you want the reflective tape to extend beyond the traced lines,
easier for taping and cutting since you're going to cut it out anyways.
Once you have it laid out, flip the paper over and cut along the line,
and there you have it, the reflective tape in the shape of the
amber reflector.
Do the same to the other reflector.
6.
From here you can align it to where the old reflector was at and stick it to
the housing.
Be sure you try your best to get this on the first try, if you peel the
reflective tape from the chrome finish, it has a chance to flake off also.
Same steps for both sides.
7.
Make sure you had sealed up any cracks and cleaned any dust/debris.
Now, with your clear silicon adhesive sealant in hand, squeeze a steady
amount on the housing where the lens will make contact.
If any part broke/chipped off during prying, use the sealant to stick it back
on, don't want any holes.
Don't be greedy with sealant, make sure you seal it up good...

Don't want moisture/rain water leaking in, I had this problem on one side.
8.
To speed up the curing of the sealant, place the lamp back into the oven
at 200F then just keep checking until the sealant becomes touchable without being tacky.
After, use the hobby knife and cut off any excessive sealant,
sand/smooth out the top lip of the lamp and touch up with black paint.
Place back onto car and admire your few hours of simple hard work.
