60% in a single tech stock (RSUs). Is this 3-ETF Ucits + 3 US based ETFs diversification plan too complicated?

Context: I'm a non-US national. Majority of my wealth is in US based tech RSU (\~60%) that has been performing above my expectations. Primarily for diversification, I want to bring it down to 30% in the next 6-8 months. Given my 20+ year timeline, I have a moderate-high risk tolerance. The new funds majorly go into IE UCITS (for estate tax and dividend efficiency).

Note: I am intentionally not seeking broad market indices for the next 5-10 years.

I'm planning to divest the 30% in this format:

|ETF|Ticker|Allocation|Reasoning/Alternative|
|:-|:-|:-|:-|
|Russell 1000 Growth UCITS|**R1GR**|50%|Growth focus, similar to SCHG, but less concentrated than the Nasdaq 100.|
|VanEck Semiconductor UCITS|**SMH**|15%|High-conviction sector play on personal belief.|
|MSCI World ex US UCITS|**EXUS**|10%|Core global diversification (similar to VXUS).|
|Momentum/Small-Cap ETFs|**SPMO/IDMO/AVDV**|25%|Split equally among these 3 for small-cap, momentum, and value exposure. (No good UCITS alternative found).|

Am I complicating the distribution and should I simplify by choosing 3-4 from the above list or maybe there are better options than this strategy?

Thank you!
