while searching for F-18 SH's stealth pod, i found F-18 SH stealth derivative by some artist on Reddit site:
Stealth Hornet: Is this the future of the F/A-18?

BTW, this is 11 years ago
Unfortunately 2D views of this 3D art are not available.
We also had a caret-intake model earlier & F-18 SH has such identical intakes.
So just for the sake of some similarity & 2xF414 engines, let's compare the F-18 SH upgrade proposed with CFT + stealth pod, with AMCA.
Otherwise 4gen vs 5gen doesn't compare, different components by different makers in different era.
The aerodynamics are also different.
This is just to see what the 2xF414 engines are pushing.
F-18 SH empty weight = base + 2x CFT = 14.5 + 2x0.4 = 15.3 tons.
Internal fuel = 6.7 tons + 3.2 tons total in 2x CFTs = 9.9 tons.
AAMs tons = 4x AIM-120 + 2x AIM-9X = 2*(162+162+85)/1000 = 0.818 tons.
AMCA AAMs tons = 4x154 Kg Astr AAMs = 0.616 tons.
Wet TWR should be at least 1.1
Bcoz 196 KN wet thrust is 62.8% of F-22's, so to have same TWR, all the weights on average should be 62.8%. The empty, fuel, weapons, external load weights can vary but total STOW & MTOW should not exceed 62.8% ideally. But AMCA's AA-STOW is 19.116 tons (65.8%), AG-STOW is 20 tons (68.3%) & MTOW is 27 tons (71%) & that of F-18 SH is even more - 90%(4+2 AAMs) & 79% MTOW. For us not having engine options YET it is a desperate compelling situation, but USA's or any maker nation's domestic engines can have more thust than export versions, which could be kept classified.
Moreover, bcoz F-18 has perpendicular wing with higher drag & lift for carrier ops, but AMCA being AF jet has better swept wings,
hence F-18 can haul more weight, but AMCA would cruise much better, longer, farther.
Let's see approximate scaled comparison b/w AMCA's caret-intake model, DSI model & F-18 SH with CFT & EWP model.
From top view, even in the F-18 non-CFT base model the forward fuselage is very skinny, the intakes start much back near LER, wing span more but area is less than AMCA, but still its empty & fuel weights are more.
From front view, AMCA appears more voluminous than non-CFT base model, but the CFT model looks little more voluminous. But the fuel weight difference is a lot - 6.5 Vs 9.9 (6.7+3.2) tons.
The EWP (External Weapons Pod) arranges 4x AAMs in 2 layers, 2x2 order. But for a brand new design, same 4 AAMs would be arranged linearly, like in AMCA or any steath jet.
