1♠ is clear, planning on JSing in clubs. Some problems with opening 2♣: 1) You start at a higher level, making it even more difficult to get both suits in. As a consequence, partner will have a tougher time evaluating his hand. 2) Partner will not expect a hand so weak in HCP/defense. 3) There is very little chance that it will go 1♠, All Pass. If you feel so strongly about (practically) forcing to game with 2♣, you can just jump to 4♣ after any balance to suggest something like this.
