You can always trim off the dead weight to compensate for the additional mass. But if you are thinking to do cold water diving in the future then the 18lb wing could be too small. In cold water diving it is the thermal protection that ultimately decide how much weight you will require = size of the wing.But if I dive with more equipment (scientific diving), do you think a 8kg/18lbs wing will be enough lift?

However, wait time, shipping, and single-tank only may be limiting factors for the OP.

There’s only wing that that I know about that is 40 lbs. lift and considered a streamlined skinny wing, and that is the Oxycheq Mach V 40#. I have one and the inner dimensions are the same as a 30 but the outside is only about 1/2” of 3/4” bigger all the way around to add enough size to make it a 40.bigger than 18lbs but less than 40lbs is a good working range, with the exception noted in my last post for warm water diving.
40lbs + wings are typically of a size where they eclipse the cylinder so much that they do what is known as taco-ing around the cylinder. This makes it difficult to reach the lower dump valve, and the excess material causes drag in the water.
Wings in the 40 to 50lbs lift range are commonly known as hybrid wings where they can be used for single or double cylinders...but hybrid wings don't work well for either. Which is why I recommend less than 40lbs for single cylinders and buy a dedicated wing for double cylinder diving if one eventually goes that route.
Not trying to belabor my point, just want you (the OP) to be informed.
